Welcome @Irenburg I do sympathize with your problems and hope @abhishek solution of re-sourcing the app improves the app launch speed. I agree that boot times are more to do with bragging rights rather than everyday practicality as @Mina implies. You can see below the leap in performance in percentage terms, comparing two notebooks of different vintage regarding chip and drive but - I too am not bothered by the odd 20 seconds – hope you will note how my 13 year old HP G60 HDD Notebook running Trisquel 8.0 gnulinux (based on ubuntu 16.04) compared to your newer machine but still with HDD – being slowed down by ubuntu 20.
LibreOffice Writer and gimp take about 2secs to launch. Perhaps @abhishek can confirm that ubuntu 20 is indeed slower than 16…? Ah; progress!
Intel® Core™2 Duo CPU T5800 @ 2.00GHz Hitachi 2.5 inch SATA hard disk drive
Very slow by today’s standards but I am told that it can be replaced with much faster drive?
Fast enough for my needs as I also have a much faster more modern Dell Latitude E6420 i7 – 256GB SSD dual boot ubuntu 16.04 with Win10-Pro - though not used hardly at all as this has a smaller screen and no number pad.
Ancient HP-G60-Notebook-PC:~$ systemd-analyze
Startup finished in 11.976s (kernel) + 22.196s (userspace) = 34.173s
Slightly faster than @abhishek Dell XPS Ubuntu edition which uses SSD – 35.704s; explain that please as I have no idea? What about my Dell Latitude speeds listed below….?
ubuntu 16.04 dell-Latitude-E6420:~$ systemd-analyze
Startup finished in 3.246s (kernel) + 10.378s (userspace) = 13.625s

Academic interesting nitty-gritty stuff – Hope @abhishek will include the involvement of the dreaded google and that backdoor in his write up on Snap…?
